RIBBON-SPOOL DEVICE FOR TYPE-WRITING MACHINES.

Specification of Letters Patent.

Patented Jan. 1 6.1912.

Application filed June 5, 1911. Serial No. 831,244.

To all when; it may concern:

Be itknow-n that I, WILLIAM R. For. a citizen of the United States, residing at Grand Itnoids, Michigan, have invented rerb tain new :tlCl useful Improvements in ltibbon-Spol Devices for 'lypedih-itiug Machines, of which the following is a speritication.

This invention relates to improvements in ribbon spool devices for typcwriting machines.

The objects of this invention are: First, to provide such a.ribbon spool that is very easily applied, which is very economical to [6 pr uce and which is very effectively supported when in osition. Second, to pro- -vide an improve construction of barrel in a ribbon spool to hich the ribbon can be. readily attached and which is especially adapted to the ribbon reverse attachments.

Objects pertaining to details will definitel y a ppear from t e detailed description to follow.

I accomplish the objects of my invention by the devicesand means described in the vfollowing specification.

.The invention is clearly defined and pointed out in the claims.

A--structure embodying the features of my invention is fully' illustrated in the. ac-

rompanying drawing, forming a part of this specification, in which:

Figure I is a detail elevation view of a I similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing. the frame of the. typewriter is always indicated by the reference numeral 1. Within the frame is the vertical ribbon spool shaft. 2, \vhirh is driven by the gears 3. the same being supported in bracket 4. This vertical shaft 2 is shouldered at 5 with sloping shoulders and terminates in n flat rectangular projection 6 at the center of the shaft at the top. The spool is made u of :1 top flange 7 and a bottom flange 8 joined together by a barrel 2). having engaging lugs portion of a typewriter with one of my im- 5 proved ribbon spools in position on a vertivnl ribbon shaft. Fig. ll is an enlarged detail vertical sectional view taken on a line corresponding to iine 2-2 of Figs. l and I] l. sln'nvingtbe ribbon nttarhing book and 40 details of construction. Fig. III is an en- I largeddetail ing in Figs. and II. Fig. [Visa ctail view somewhat enlarged, of the barrel blank.

. r Fig. V is a detail view somewhat enlarged,

Fig. VII is. e dcta il sectional .view on aJine cot-res ending to line 5-5 5 of Fig. VI. Fig.1 V II is a detail transverse sectional view on a line'corresponding to line 8-8 of Figs. VI and VIII In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and {dun view of the spool appear l(l-](l at the top and bottom for coupling these flanges together. The lower flange 8 isms-formed centrally at H to receive the shaft 2. and the u iper flange is conical at the renter l2 \\'lll('l rontnins a central rectangular opening 13 to receive the rectangu lar end i o the shaft, so that-in applying the spool it is only necessary to drop it onto the end of the shaft. when as soon as the shaft turns. owing to the conical form, the spool will move. to the central positionso that it will drop into place and-be engaged by the shaft, and no further attention need llt given to the spool than to drop it onto the shaft. The barrel 9 of the spool being made of sheet metal, it very readily lends itself to the formation of the. attaching de-. vice which consists oi a book 23 which is fornu-d by punching out an aperture 22 in th lnnl of the some. and rolling it up as indicated. in this way the ribbon can be inserted through tbevaperturc and will be engaged by the. book 23. The barrel is not made quite. complete, the ends being a little Htfl'lttttlittl, forming a space 24, as seen in Fig. V. This is of advantage and makes the structure specially adapted for the trip ping devices for reversing the ribbon on t 1e Fox typewriter. This particular arrangement of detail is of importance on this account. because of its great economy and simplicity, and because also it is a very effective device.

In applying the structure to a'horizontol shaft, 9. little more attention is necessary than is required to ticnl ribbon shaft.

In Fig. VI I show a horizontal. shaft adapted to this improved spool. A sleeve,14 fits on the shaft 15 and is capable of longi-' tudinul adiustment, being guided thereon place the same on a verby the rib l7 engaging the longitudinal grooves 18, the sieeve being urged outwardly by the spring 16. The outer end of the sleeve 14. is compressed at It) to form the rectangular projection at the end of the shaiit, which projects into the slot t-i in the conical side 1; 21 is recessed at 2" to receive the pr je tion 19, these parts definitely appearing in Flew. VI and VII and VIII. To insert the spool, the shaft sleeve 14 is pushed against the spring 16, the spool is inserted, and the sleeveisin-ged to position by the spring.

From tins deacription it will be seen that my structure is capable of comiderablc modification and is adapted for \nliolts uses and relations in a. typewriter.

Having thus what I claim as new Letters Patent is:

1. In a. typewriting machine, the combination of a ribbon spool comprising side flan es, one of which projects conically out- Wfll't with a noi'i-circular central aperture; and a sheet metal barrel connecting said flanges, open at one side, scroll of sheet metal, said barrel having an aperture formed in the side thereof and containing a hook member formed within said aperture and integral with said barrel fo engaging the end of the ribbon, enacting for e purpose specified.

2. In a typewriting machine, the combination of a ribbon spool comprising side flanges; and a barrel connecting said flanges. consisting of a scroll of sheet metal, open atone side, said sheet metal scroll having an aperture for led in the side thereof and containing a hook member formed within said aperture and integral with said barr 'l and desire to sctlll't by of the spool. The hort haft consisting of a dcacribcd my invention, i

' ectu-n and a central o i l l l for engaging the end of the ribbon, (Utlttillfi for the purpose 5 )ecified. 3. In l a typewriting machine, the combination of a ribbon spool comprising side flanges; and a barrel connecting said flanges, consisting of a hCl'Ull of sheet metal, having an aperture formed in the aide thereof and containing a hook member formed within said aperture and integral with said barrel for engaging the end of the ribbon, enacting for the purpose specified.

I. In a t 'pewriting machine, the combination of a ribbon spool comprising a scrolllike barrel and side flanges. one of which ide flanges projects ironically ()HlWzltgl with a non-circular ccnlral aperture. the mid conical flange projection being |iitht-1ai to guide the spool onto the \pool .diat't.

:7. In a pool for a t 'pcu'fltcr. the combination of llilhlgts scoured t gether by a altitabhbarrel, one flange haiinga conical prolong slot, and a riba rcctangnlm' shoulbon sptml shaft with aid o l ng; slot, as

dcred end to engage specified.

6. In a ribbon spool for a t \p \\'ritcr, the combination of flanges secured together by a nuilaldc barrel, one flange havine a conical projection and a non-circular opening, and a ribbon spool shaft: with the end noneircular in clOss section to engage said slot, as specified.

7. In a ribbon spool for a typewriter, the combination of flanges secured together by a suitable barrel of a scroll of sheet metal, one flange having a conical projection adapted to guide the spool into working the ribbon shaft; by reacting with the end of the shaft within the barrel, as specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
